Abstract
A glenoid implant that is 3D-printed or machined from ceramic and/or metal as a substitute for an autograft or allograft in a surgical repair. Structural supports composed of metal are designed in the interior of the implant for support during implantation and post-operation. The remainder of the volume of the implant is composed of a material having optimal pore structure for rapid bone integration and healing.
Claims13
A surgical implant comprising:
- a substantially rectangular body having a solid structural support and a porous region surrounding the structural support, the body further having a first surface, a second surface opposite the first surface, and at least two through holes extending through the structural support from the first surface to the second surface;
- a cylinder disposed within each of the at least two through holes, the cylinder comprising a telescoping peg configured to allow passage of a suture through the cylinder;
- and
- a breakable connection point between the body and the cylinder, the connection point configured to secure the telescoping peg within the through hole until a force applied to the connection point allows the telescoping peg to extend from the second surface into a mating hole in bone.

A method of glenoid instability repair comprising:
- forming at least two axially-aligned passages from a first surface to a second surface of a glenoid;
- aligning at least two through holes of an implant with the at least two passages in the glenoid, the implant further comprising:
- a substantially rectangular body having a solid structural support and a porous region surrounding the structural support, the body further having a first surface, a second surface opposite the first surface, the at least two through holes extending through the structural support from the first surface to the second surface, and a cylinder disposed within each of the at least two through holes, the cylinder comprising a telescoping peg configured to allow passage of a suture through the cylinder;
- applying a force to break a connection point between the peg and the implant body, causing the peg to extend from the second surface of the body into one of the at least two passages of the glenoid.
